Newgarden will be re-evaluated following practice to determine a course of action for the remainder of the race weekend. Should Newgarden not be able to participate in the KOHLER Grand Prix, Ed Carpenter Racing will have JR Hildebrand at Road America to drive the No. 21 Direct Supply Chevrolet.

Newgarden sustained a fractured right clavicle and a small fracture in his right hand in an incident in the suspended Firestone 600 at Texas Motor Speedway on June 12. He has been under the care of the Indiana Orthopedic Hospital by INDYCAR consultant Dr. Kevin Scheid.

Practice for the KOHLER Grand Prix begins at noon ET Friday with a live telecast on NBCSN. A second practice is scheduled for 4 p.m. ET and will be streamed live on RaceControl.IndyCar.com. Qualifying takes place Saturday with the 50-lap race set for Sunday (12:30 p.m. ET, NBCSN).
